My daughter just bought a used Jeep Grand Cherokee and I'm wondering what oil you guys would suggest. It's a 2000 model, 4.7L non-HO V8, 70,000 miles. The UOA section was no help.
We need to get a manual since it didn't come with one, but I assume 5W-30 or 10W-30 were specified when it was built.
We would rather use a synthetic and I'm wondering if the 4.7L would do better with one of the 5W-40 oils like the 4.0L inline six seems to, or if I should stick to 5W-30.
Suggestions welcome but no GC please. It's not readily available around here and I can't see my daughter or her husband driving around searching for it.
